How to Use the Transmitter

General information

The Transmitter applies an electrical current (signal) onto a buried metallic service, which
enables the service to be traced and identified by the Locator operating in the same mode.
There are three operating modes for onsite flexibility:
• 8 kHz for congested site operation
• 33 kHz for general usage
• Combined 8 kHz and 33 kHz available in Connection mode, enabling rapid selection and
convenience on congested sites. The Locator can be used in either mode.
Active tracing is a term frequently used when a Transmitter is used to apply a signal to a
service enabling it to be traced. The use of a Transmitter will greatly improve the detection
of services especially ones which may not have a signal on them.
The signal from the Transmitter can be applied to services in two ways:
• Induction mode (8 kHz or 33 kHz):
Induction is a quick and simple way to apply a signal to a service without the need to
make any physical connection to it. The Transmitter uses an internal aerial to transmit
the signal, therefore it should be noted that the signal will apply itself to additional serv-
ices within close proximity to the Transmitter.
• Connection mode (8 kHz or 33 kHz or combinded 8 kHz and 33 kHz):
This is the most efficient way of applying a signal to a service, and should be used when-
ever possible. The Transmitter's cable set or any of the available accessories are
connected to the service which is to be traced or identified.
